Mumbai, December 2025 - Advent, a leading manufacturer and supplier of specialty chemicals, peptide intermediates, and pharmaceutical working standards, is pleased to announce the expansion of its peptide chemistry portfolio with the introduction of high-purity Fmoc-Arg(Pbf)-Ol, a dual-protected amino alcohol derivative engineered for advanced solid-phase peptide synthesis (SPPS) and analytical applications.
Fmoc-Arg(Pbf)-Ol—chemically known as (9H-fluoren-9-yl)methyl (S)-(1-hydroxy-5-(3-((2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran-5-yl)sulfonyl)guanidino)pentan-2-yl)carbamate)—combines Fmoc protection at the N-terminus with Pbf protection on the guanidino side chain. This dual-protection strategy ensures exceptional stability during SPPS, minimizes side reactions, and improves the accuracy and reproducibility of arginine-containing peptide assemblies. The presence of an alcohol (-Ol) functionality further enhances the molecule’s versatility, allowing adaptation to fragment coupling, backbone modification, and the preparation of complex peptide intermediates.
Manufactured by Advent from milligram to gram scale, Fmoc-Arg(Pbf)-Ol is supplied at purity levels exceeding 98%, making it a dependable choice for both research-scale and commercial peptide programs. Each batch is accompanied by complete analytical characterization, including ¹H NMR, Mass, IR, TGA, and additional supportive data required for regulatory and quality benchmarking purposes. This enables its reliable use as a Working Standard for method development, system suitability testing, impurity profiling, and purity comparison.
“As peptide therapeutics continue to gain prominence, the need for high-quality, dual-protected amino acid derivatives has become essential. Fmoc-Arg(Pbf)-Ol reflects our commitment to delivering robust, reproducible, and fully characterized materials to support global pharma and biotech ecosystems,” said Dr. Rashmi Ranjan Mohanty, Director- Technical for Advent.
He further added, “Our ability to scale this specialized molecule while maintaining consistent purity and analytical clarity provides our customers with a strong advantage in peptide development and manufacturing.”
Advent currently supplies Fmoc-Arg(Pbf)-Ol to leading pharmaceutical companies, CDMOs, CROs, and peptide manufacturers across India and international markets. The launch further strengthens the company’s position as a trusted partner for advanced peptide intermediates, working standards, and specialty chemical solutions.
